  • This provides a compact moulding station comprising multiple web moulds arranged at multiple levels, thereby increasing the production capacity without increasing the re quired production area.
  • This allows large shear webs for large wind turbine blades to be manufactured simultaneously without taking up additional production space. This al so allows multiple production lines to be arranged within the same manufacturing facili ty.
  • said upper level is formed by a working platform extend ing in a longitudinal direction and in a transverse direction, wherein said first web mould is arranged below said working platform.
  • the manufacturing facility may be constructed as a permanent structure or a temporary structure defining an overall production area.

  • the upper level is defined as an intermediate floor located be tween the ground level and a ceiling of the production area which defines an upper lev el floor space.
  • a first upper level may be located above the ground level and a further second upper level may be located above the first upper level, and so forth. This increases the total floor space for the production lines.

This allows the blade shell parts and shear webs to be manufactured in a combined production line. Alternatively, one or more blade moulds and an associated lifting system may be in stalled before and further on the working platform. This allows the blade shell parts to be manufactured at multiple levels.
  • At least a third web mould is further arranged at the ground level relative to the first web mould and/or at the upper level relative to the sec ond web mould, the third web mould comprising a moulding surface for moulding at least a third shear web.

  • This arrangement is e.g. suited for parallel production of different sets of shear web segments for different wind turbine blades. Further, any web moulds not currently used in production may be stored with the manufacturing facility without limiting the produc tion capacity, thereby reducing the production downtime.
  • one or more web moulds of a set may extend in an inclined an gle relative to the longitudinal direction. This may e.g. be suited for pre-bend wind tur bine blades.
  • one web mould, e.g. a web mould for a first shear web seg ment, of a set may extend in a first direction while another web mould, e.g. a web mould for a second shear web segment, of said set may extend in a second direction.

  • Temporary spacer means e.g. interconnecting or telescopic rods, may be fitted between the shear webs to maintain the distance between the shear webs during installation.
  • the support frame with shear webs may then transferred to the blade shell and in stalled. Once the installation process is completed, the spacer means and the support frame may be removed and reused for another set of shear webs. This allows the set of shear webs to be assembled in the moulding station prior to installation.

  • One object of the invention is also achieved by a method of manufacturing a shear web for a wind turbine blade, the method comprises the steps of:
  • a moulding station comprising a first web mould and at least a second web mould
  • said manufacturing of the first shear web is performed at a ground level while said fur- ther manufacturing of the second shear web is performed at an upper level, the upper level being located above the ground level.
  • This provides a method of manufacturing multiple set of shear webs at multiple levels, thereby reducing the cycle time for producing multiple wind turbine blades at the same manufacturing facility. This increases the production capacity of the moulding station without increasing the required production area.
  • the individual shear webs for a particular wind turbine blade can thus be produced simultaneously in different web moulds. This reduces the total cycle time.
  • the shear webs are afterwards transferred directly to the blade mould or cradle for installation or to a post-moulding sub-station for assembly prior to installation.
  • shear webs or shear web segments can advantageously be manufactured using the present invention without having to increase the production area.
  • the shear webs for one type of wind turbine blade are thus manufactured in one production line, e.g. on the upper level, while the shear webs for another type of wind turbine blade are manu factured in another production line, e.g. on the ground level.

Abstract

La présente invention concerne un poste de moulage (19) et un procédé mettant en œuvre un tel poste de moulage (19), le poste de moulage (19) comprenant un premier moule d'âme (23) et un second moule d'âme (24) disposés sur différents niveaux. Le premier moule d'âme (23) est conçu pour fabriquer une première âme de cisaillement et le second moule d'âme (24) est conçu pour fabriquer une seconde âme de cisaillement. Les première et seconde âmes de cisaillement sont déplacées vers un sous-poste de post-moulage (36) en vue d'étapes d'assemblage ou de finition, ou vers une zone de transfert. Les ensembles d'âmes de cisaillement peuvent être fabriqués à de multiples niveaux, ce qui permet d'augmenter la capacité de production.
